That is the kind of pump I am thinking of putting in... Run the

basement. They are becoming more popular in dry areas and can be run
with a lot less power than a 3/4 horse, 240v pump..

I bet it is not that much less. You still bump up against physics.

Yeah, and I can't afford a learning curve..

You can do some rough calculations based on the cu/ft per min of the
compressor at 100 PSI (roughly 200' head) and convert that to gpm of
the water at 8 times that but I doubt it actually works that
efficiently. This would be the max possible.

That sounds about right, the video I saw had a 200 foot well with 85
psi, and it was glugging a cup and a half glug, every few seconds... the
guy said it was doing about 4 gpm.. Most of the vids I have seen look
pretty stable as to the concept. The flow is not steady, and I am sure
it's noisy, but it does seem to work with very simple setup. Another
concern is water level in the well, there needs to be a few feet of pipe
below the air inlet on the pipe for it to work right. At the same time I
am still working on getting that old pipe out. Got the Tee you
recommended on today, and will try to pull the cap when I get home
tonight and can build a staging to hold the pipe and tee....
